PROCESS FOR PREPARING A HYDROCONVERSION CATALYST, CATALYST THUS OBTAINED AND USE THEREOF IN A HYDROCONVERSION PROCESS |
摘要 |
The invention relates to a process for preparing a hydroconversion catalyst based on a modified zeolite of the FAU framework type with preserved crystallinity and microporosity, comprising the steps of:
A—preparation of a modified zeolite of the FAU framework type, whose intracrystalline structure presents at least one network of micropores, at least one network of small mesopores with a mean diameter of 2 to 5 nm and at least one network of large mesopores with a mean diameter of 10 to 50 nm; these various networks being interconnected;B—mixing the zeolite with a binder, shaping the mixture, and then calcining;C—impregnation of the shaped zeolite with at least one compound of a catalytic metal chosen from compounds of a metal from group VIII and/or from group VIB, in acidic medium, provided that at least one compound of a catalytic metal is soluble within said acidic medium and that the acid acts as a complexing or chelating agent for at least one compound of a catalytic metal.;The invention also relates to a catalyst obtained via this process and also to the use thereof. |

1. Process for preparing a hydroconversion catalyst based on a modified zeolite of the FAU framework type with preserved crystallinity and interconnected trimodal porosity, comprising the steps of:
A—preparation of a modified zeolite of the FAU framework type, whose intracrystalline structure presents at least one network of micropores, at least one network of small mesopores with a mean diameter of 2 to 5 nm and at least one network of large mesopores with a mean diameter of 10 to 50 nm; these various networks being interconnected; B—mixing the zeolite with a binder, shaping the mixture, and then calcining; C—impregnation of the shaped zeolite with at least one compound of a catalytic metal chosen from compounds of a metal from group VIII and/or from group VIB, in acidic medium, provided that at least one compound of a catalytic metal is soluble within said acidic medium and that the acid acts as a complexing or chelating agent for at least one compound of a catalytic metal. |
